# Unit tests for make(1)

# test:
#	run 'all', and compare to expected results

# Settable variables

# TEST_MAKE
#	The make program to be tested.

# Adding a test case
#
# Each feature should get its own set of tests in its own suitably
# named makefile (*.mk), with its own set of expected results (*.exp),
# and it should be added to the TESTS list.
